Make alterations to existing iOS app

My app is not working with 10.0.2. It needs a "restore purchases button added to it" and it needs to have In-app purchase capabilities. I will need it uploaded on my developer account as well.

The App was made with Corona SDK

this is the message I got from apple when I tried to upload it to the itunes store:

"We discovered one or more bugs in your app when reviewed on an iPad and iPhone running iOS 10.0.2 on Wi-Fi connected to an IPv6 network.

Specifically, we are unable to purchase any of the In-App Purchase products.

Next steps:

Please run your app on a device while connected to an IPv6 network (all apps must support IPv6) to identify the issue(s), then revise and resubmit your app for review.

We found that your app offers In-App Purchase(s) that can be restored but does not include a "Restore Purchases" feature to allow users to restore the previously purchased In-App Purchase(s), as specified in the "Restoring Purchase Products" section of the In-App Purchase Programming Guide

"Users restore transactions to maintain access to content they've already purchased. For example, when they upgrade to a new phone, they don't lose all of the items they purchased on the old phone. Include some mechanism in your app to let the user restore their purchases, such as a Restore Purchases button."

To restore previously purchased In-App Purchase products, it would be appropriate to provide a "Restore" button and initiate the restore process when the "Restore" button is tapped by the user.
